Hello,

I am trying to send entire .script through Primary Client (30001 port) using a ROS service. The ROS service accepts a script with ‘def’ and ‘end’ and sends it on port 30001 via TCP socket. I want to add an additional functionality to control the execution on this script, for example, I would like to start/pause/stop this script using ROS. It would be very helpful if nyone who has thought on the same lines can provide some inputs.

Thanks in advance,
